Our team

Over 17 years experience in various roles in IT have allowed me to gain a comprehensive understanding of the industry and its short comings. These form the core foundation of my strategic planning and decision making to drive the success of Swissworx and position the company in the right niche market.

While working for small to large size enterprises in multiple countries I have had the privilege to build development teams of highly skilled individuals. I demonstrated to peers and senior management my leadership and communication skills and the ability to deliver software solutions on time and under budget.

Despite my move into an executive role I have never lost my interest and passion for software development in all this years. When time permits I find myself still doing some hands-on development which gives me an excellent understanding of the technical solutions that we deliver for our clients. This also allows me to ensure best practises are followed and the team adheres to high coding standards.
